Islamic education plays a vital role in shaping generations with strong character, knowledge, and noble values; however, in the era of globalization and technological advancement, Islamic educational institutions face significant challenges in maintaining and improving service quality. This study aims to analyze the implementation of collaborative management in improving the quality of Islamic education services, focusing on its forms of application, supporting and inhibiting factors, as well as its contribution to educational outcomes. Employing a qualitative case study approach, data were collected through interviews, observations, documentation, and supporting questionnaires, then analyzed using triangulation techniques and thematic coding. The findings indicate that collaborative management is realized through regular consultations, parental involvement, cooperation among teachers, and the active participation of external stakeholders, which collectively enhance academic performance, strengthen character development, and reduce student absenteeism. Key supporting factors include visionary leadership, a culture of consultation, and community support, while challenges consist of limited resources, teachers’ heavy workload, and communication barriers. The study provides a theoretical contribution by integrating Islamic values such as shura (consultation), ukhuwah (brotherhood), and ta’awun (mutual assistance) into the framework of collaborative management, and a practical contribution by offering an adaptive and inclusive participatory management model. These findings are expected to serve as a reference for advancing Islamic educational management theory and policymaking to sustainably improve the quality of educational services.
